Why Choose the ABB 2TLA020072R0600 URAX-E1 Safe Input?
The ABB 2TLA020072R0600, designated URAX-E1, is a safe input AS-i slave module for two-hand control devices. Identified by ABB reference 20-072-06 and classified within the Safety PLC product group, it is specifically designed for two-hand control applications according to EN 574 Type IIIC.
The URAX-E1 provides two monitored inputs for each hand, comprising one normally closed and one normally open contact channel per hand. For safe activation, all four inputs must be enabled within 0.5 s. The module continuously monitors the input conditions and, following deactivation, requires all four inputs to return to their inactive states before another safe activation can occur.
Powered directly from the yellow AS-i cable at a nominal 30 V DC, the URAX-E1 combines AS-Interface connectivity with a rugged IP67 enclosure for decentralised machine installation. Its safety architecture supports applications up to SIL 3 and PL e / Category 4 when correctly incorporated into the complete safety system.

- Yellow and black IP67 industrial enclosure.
Dedicated Monitoring for Two-Hand Safety Controls
The ABB URAX-E1 is designed specifically for machinery where an operator must actuate a two-hand control before a hazardous movement can begin. Each hand-control device is monitored through separate normally open and normally closed contacts. All four input conditions must become valid within 0.5 s before the URAX-E1 generates its safety code, helping ensure that the two controls are intentionally operated together.
If the URAX-E1 is deactivated and stops generating its safety code, all four monitored inputs must first return to their inactive conditions before another activation is accepted. This monitored release-and-reactivation sequence supports the anti-tie-down and synchronisation requirements associated with two-hand machine-control applications.
Typical Applications
- Industrial two-hand control stations.
- Press and forming machinery.
- Cutting and processing machines requiring two-hand initiation.
- Assembly machinery with hazardous operating cycles.
- AS-i Safety at Work installations.
- Decentralised machine-safety systems requiring monitored two-hand controls.

Frequently Asked Questions
What is the ABB 2TLA020072R0600 URAX-E1 used for?
The ABB URAX-E1 is a safe input AS-i slave for two-hand control devices, specifically intended for two-hand safety controls according to EN 574 Type IIIC.
How many inputs does the URAX-E1 monitor?
The URAX-E1 monitors four contact inputs: one normally closed and one normally open input for the left-hand control, and one normally closed and one normally open input for the right-hand control.
How quickly must both hand controls be activated?
For safe activation, all four monitored input conditions must be enabled within 0.5 s. If this synchronisation condition is not satisfied, the URAX-E1 does not generate the required safety code.
What supply voltage does the ABB URAX-E1 require?
The URAX-E1 is powered from the yellow AS-i cable at a nominal 30 V DC, with a specified operating range of 26.5–31.6 V DC.
What safety level does the ABB 2TLA020072R0600 support?
The URAX-E1 supports applications up to SIL 3 according to EN 62061 and PL e / Category 4 according to EN ISO 13849-1 when correctly incorporated into the complete safety system.
